Last May at Google I/O, we launched Music Beta by Google with a clear ambition: to help people access their music collections easily from any device. Music Beta enabled you to upload your personal music collection (up to 20,000 songs) for free to the cloud so you could stream it anywhere, any time. Today, the beta service evolves into a broader platform: Google Music. Google Music is about discovering, purchasing, sharing and enjoying digital music in new, innovative and personalized ways.

Google Music helps you spend more time listening to your collection and less time managing it. We automatically sync your entire music library—both purchases and uploads—across all your devices so you don't have to worry about cables, file transfers or running out of storage space. We’ll keep your playlists intact, too, so your “Chill” playlist is always your “Chill” playlist, whether you’re on your laptop, tablet or phone. You can even select the specific artists, albums and playlists you want to listen to when you're offline.

Purchase and share
We also want to make it easy and seamless for you to grow your music collection. Today, we added a new music store in Android Market, fully integrated with Google Music.

The store offers more than 13 million tracks from artists on Universal Music Group, Sony Music Entertainment, EMI, and the global independent rights agency Merlin as well as over 1,000 prominent independent labels including Merge Records, Warp Records, Matador Records, XL Recordings and Naxos. We’ve also partnered with the world's largest digital distributors of independent music including IODA, INgrooves, The Orchard and Believe Digital.

You can purchase individual songs or entire albums right from your computer or your Android device and they’ll be added instantly to your Google Music library, and accessible anywhere.

Good music makes you want to turn up the volume, but great music makes you want to roll down the windows and blast it for everyone. We captured this sentiment by giving you the ability to share a free full play of a purchased song with your friends on Google+.

Exclusively on Google Music
We’re celebrating our launch with a variety of music that you won’t find anywhere else, much of it free. There’s something for everyone, with a variety of free tracks to choose from:

The Rolling Stones are offering an exclusive, never-before-released live concert album, Brussels Affair (Live, 1973), including a free single, “Dancing with Mr. D.” This is the first of six in an unreleased concert series that will be made available exclusively through Google Music over the coming months.

Artist hub
Whether you’re on a label or the do-it-yourself variety, artists are at the heart of Google Music. With the Google Music artist hub, any artist who has all the necessary rights can distribute his or her own music on our platform, and use the artist hub interface to build an artist page, upload original tracks, set prices and sell content directly to fans—essentially becoming the manager of their own far-reaching music store. This goes for new artists as well as established independent artists, like Tiesto, who debuts a new single on Google Music today.

Starting today, Google Music is open in the U.S. at market.android.com, and over the next few days, we will roll out the music store to Android Market on devices running Android 2.2 and above. You can also pick up the new music app from Android Market and start listening to your music on your phone or tablet today. And don’t forget to turn your speakers up to eleven.
